Trong các tòa nhà thương mại lớn như trung tâm mua sắm, the AHF Bộ lọc điều hòa hoạt động plays a crucial role in improving power quality and ensuring the stable and efficient operation of the electrical system. Its key functions include:
Harmonic Suppression
Sources of Harmonics in Shopping Malls:
LED lighting, Thang máy, air conditioning systems, and UPS (Uninterruptible Power Supply) generate significant harmonic distortion due to their non-linear loads.
Electronic devices in retail stores (such as POS systems, displays, and sound systems) also contribute to harmonic pollution.
Role of AHF:
It continuously monitors the power system and generates compensating currents with equal magnitude but opposite phase to cancel out harmonics.
This helps maintain sinusoidal voltage and current waveforms, reducing power losses and improving overall power quality.

Reactive Power Demand in Shopping Malls:
Inductive loads such as motors in HVAC systems, fans, and water pumps require reactive power to operate efficiently.
Traditional reactive power compensation methods (such as capacitor banks) have slow response times and lack real-time adjustment.
Role of Active Harmonic Filter:
AHF provides dynamic reactive power compensation, instantly adjusting reactive power to improve power factor.
This reduces reactive power losses and minimizes penalties imposed by utilities for poor power factor.
Mitigation of Three-Phase Imbalance
Causes of Three-Phase Imbalance in Shopping Malls:
The presence of numerous single-phase loads (such as lighting, computers, and air conditioning) leads to uneven phase loading, causing excessive neutral current.
Role of AHF Active Harmonic Filter:
It dynamically adjusts the current distribution across phases, balancing the load and reducing unbalanced currents.
This enhances system efficiency, protects transformers, and extends the lifespan of electrical components.
Reduction of Power System Resonance Risks
Resonance Issues in Commercial Buildings:
The interaction between network inductance and capacitance can lead to harmonic resonance, causing overheating, equipment malfunctions, or even damage.
Role of AHF Active Harmonic Filter:
By actively suppressing harmonic currents, AHF minimizes resonance risks and ensures the stable operation of the power system.
This prevents excessive loading of cables, transformers, and capacitors, reducing the risk of premature aging or failure.
Extending Equipment Lifespan and Reducing Maintenance Costs
Minimizes harmonic-induced damage: Reduces additional heating and stress on electrical equipment such as transformers, dây cáp, and motors, extending their lifespan.
Prevents unexpected failures and downtime: Reduces false tripping and malfunctions caused by harmonics, lowering maintenance costs.
Improves energy efficiency: Optimizes power quality, reducing both reactive power losses and unnecessary energy consumption.
In Conclusion, in commercial buildings such as shopping malls, AHF Active Harmonic Filter is an essential solution for mitigating harmonics, providing dynamic reactive power compensation, balancing three-phase loads, and enhancing power quality. By improving the efficiency and reliability of the power system, AHF Active Harmonic Filter reduces operational costs, prevents equipment failures, and ensures a stable energy supply, making it a vital investment for modern commercial facilities.
